I don't think we should assume 4♥ is a preempt here. I can think of a lot of hands holding two small spades on this auction that would think 4♥ is a good contract, have little/no slam interest, and want to minimize the chance of opponents competing in ♠. I realize this last part can sound like "preempt", but this auction is more likely to contain an outside ace (A♣) etc... We should adjust our perspective according?
My agreement would have X as negative here, I'd probably bid 4NT, asking partner to bid their preferred minor, thinking something like the following:
5♣ --> Bid 5♦: Should clearly show a hand like this? Since I never had any intention to play 5♣. Partner can raise when they feel strongly about their hand.
5♦ --> Bid 5♥: I didn't convert to 5♠ so this is a clear slam force looking for grand in diamonds. It should show a first round control in ♥, since surely 5NT really can't be a King ask, that's just a general "Pick-The-Best-Slam" bid. I've also right sided this contract for partner to receive a club lead up to their hand when missing the A♣.
I don't agree with insisting on playing slam here, KX♦and the A♣ in the 4♥ bidder's hand and you've got no hope. There is no reason why they don't hold those cards whatsoever. I'd personally opt for a more constructive sequence as described.
The OP described the double as 'showing values', which is pretty much the standard usage these days, even among non-expert tournament players, at least in NA. Partner will NOT have a heart stack: the trade-off for the value showing double is that with a penalty double one passes and hopes for a reopening double.
Also, the card-showing double is usually played as showing what are known as 'transferable values', that is to say cards that will work well on offence, should opener have extreme shape, and also on defence, should opener be flat. Opener is expected to pass with a balanced hand and to bid with good shape.
Partner knows that is what his double promises. He cannot, for example, hold something like xx Qxx 10xxx KQxx. That is not a double. By the way, 6D has play opposite that, tho one would not want to be there.
Don't let your fears that the 4H bidder has defence detract from your efforts to construct hands for partner. Trust partner, rather than fear LHO.
Partner should have a near-opener, with no primary spade support, no penalty double of 4H, and a willingness to hear you bid 5D on something like AKxxxx x AQxxx x.
You have a far better hand than that: trust partner, not the opps.
Btw, the last 4H overcall I saw against 1S was two weeks ago in the North American Seniors Swiss at the NABC in Las Vegas. I didn't get to make it because my partner opened 3C in 1st chair with x xxx xx KJxxxxx (favourable, we tend to bid a lot). At the other table, that hand passed and my hand had to deal with a 1S opening, looking at xx AKJ10xxxx x 10x. Now, that's what a 4H bid looks like, far more often than a hand with the side club Ace and diamond King!
Sure, overcaller COULD hold those cards....until partner bid. Once partner showed length and strength in the minors, not committing to slam is frankly inexplicable.
